Significant amount of work has been carried out to quantify entanglement, which for the two particle case has been well understood [1]}. While there exists several entanglement measures for pure and mixed two qubit systems such as, concurrence [2]}, 3-tangle [3]}, entanglement of formation [4]}, Schmidt number [5]} etc., there is no straightforward and unique way to characterize entanglement in multipartite setting. Among all these measures, concurrence is one of the most widely used, as it provides necessary and sufficient conditions for separability for a general pair of qubits. For arbitrary dimensions, the concurrence for multiparticle pure state was generalised by Rungta et al. [6]} and is known as "I-Concurrence". Mintert et al. [7]} carried out the general characterization of concurrence for multipartite quantum systems, showing that it is qualitatively different from other quantum correlations.
